Elephant and Castle

A public-house sign at Newington, said to derive its name from
the skeleton of an elephant dug up near Battle Bridge in 1714. A
flint-headed spear lay by the remains, whence it is conjectured that
the creature was killed by the British in a fight with the Romans. (The Times.)

There is another public-house with the same sign in St. Pancras,
probably intended to represent an elephant with a howdah.
